The name of the mutation, del 69-70, or 69-70 del, or other similar notations, refers to the deletion of amino acid at position 69 to 70. The mutation is found in the Alpha variant, and could lead to "spike gene target failure" and result in false negative result in PCR virus test. [270]
The test matches RNA in three locations, and stopped working for the spike gene due to the HV 69–70 deletion—a deletion of the amino acids histidine and valine in positions 69 and 70, respectively [262] —in the spike protein of lineage B.1.1.7. This made preliminary identification easier because it could be better suspected which cases ...
Li–Fraumeni syndrome (LFS) is a rare, autosomal dominant, hereditary disorder [1] that predisposes carriers to cancer development.It was named after two American physicians, Frederick Pei Li and Joseph F. Fraumeni Jr., who first recognized the syndrome after reviewing the medical records and death certificates of childhood rhabdomyosarcoma patients. [2]
It has mutations in the gene encoding the SARS-CoV-2 spike protein [6] causing the substitutions T478K, P681R and L452R, [7] [8] which are known to affect transmissibility of the virus as well as whether it can be neutralised by antibodies for previously circulating variants of the COVID-19 virus.

The Automated Classification of Medical Entities program automates the underlying cause-of-death coding rules. The input to ACME is the multiple cause-of-death codes assigned to each entity (e.g., disease condition, accident, or injury) listed on cause-of-death certifications, preserving the location and order as reported by the certifier.
Mutations, however, may not be as frequent in cancers as epigenetic alterations. An average cancer of the breast or colon can have about 60 to 70 protein-altering mutations, of which about three or four may be "driver" mutations and the remaining ones may be "passenger" mutations. [117]
Indel (insertion-deletion) is a molecular biology term for an insertion or deletion of bases in the genome of an organism. Indels ≥ 50 bases in length are classified as structural variants. [1] [2] In coding regions of the genome, unless the length of an indel is a multiple of 3, it will produce a frameshift mutation.
The gene encoding CD69 is located in the NK gene complex on chromosome 6 and chromosome 12 in mice and humans respectively. [7] Activation signaling pathways in lymphocytes, NK cells, dendritic cells and other cell types upregulate transcription factors, such as NF-κB, ERG-1 (erythroblast transformation-specific related gene-1), and AP-1 (activator protein), in order to promote the ...
